I disgaree with that statement in that they should at least be regularly deburred - but then you wnet & said as much in your following post.
BTW, GrahamN is training/racing a few times a week on a dryslope hence his edge attrition rate.

Well, the person's real but it's just a made up name, see?

primoz, trust me, having no experience of skiing on plastic is a good thing

GrahamN, thanks for the tips and thanks everyone else for the links and advice. I took the skis in to one of the very best service repair places in queenstown today - it's 25 dollars for a service - just under £10 so I think for the sake of a few pound I will leave it to the pro's in future!
spyderjon, as the others have pointed out, in NZ at the mo. I'm sure you're very good so maybe when I'm back in the UK!

NomadicBoo, That sounds good value. It's worth having a chat with the service guys and see how they do the service. Try to get shops who service by hand rather than by machine your skis will last longer and not be changed after servicing. Some of the ski shops in France have big pictures of their ski tuning machines in the window advertising their services. I read them as warning signs 
You can wax as much as you like without doing harm but edges do just as much as they need, deburring little and often as per Spyderjons post at the top of this page.
Tuning is not difficult but its also not dificult to mess up either.
The other thing you might have done whilst doing your edges was use a guide with the wrong angle. If the angle of your guide is less than that of your side edge you will actually make you edges more blunt.

That's not true anymore. Edge tuning in WC is today done almost exclusively with machines, and at least around here (Slovenia) some services started to use same machines last winter, so I doubt it would be much different somewhere else. Edges prepared this way last much longer (even for racers), not to mention they are prepared more accurately, and sometimes even the way they couldn't be prepared before by hand. But I agree... Wintersteiger (just for example) do it all machines are not the way to go

Thats the type of thing I was on about all right.

No it won't, it will just take off metal from further up the side edge, without doing anything for the edge sharpness itself - until you take enough off, in which case you get a nice sharp edge at the finer angle.
Interesting observations this weekend regarding the amount and way I sharpen my edges. Yesterday we had a very straight course (after one sharp turn at the start), and all I needed to do all day was just touch up the edge between each run with a diamond file. Sharpening them yesterday evening though in readiness for today's race required a load of edge taken off to get anything remotely sharp.
Today's course had a pretty turny section coming out of a very fast combination (with a roller thrown in for good measure). So I made sure I gave the edges a good tune up after my warm-up session. The first run through the course I set up for the first of those turns with a not bad line (maybe not perfect, but good enough) - but my skis just went sideways with nowhere near enough grip to make the turn. So back to the tuning bench, where I remembered that the thing I'd forgotten on that first turn was to finish off with a diamond stone to exaggerate the burr/hook on the edge. Second run, having done that - grip to spare (and my scrabbling around to stay in at at the bottom of the course was entirely due to my own incompetence). Third run, the same (and I finally managed to get a gold-medal run time   ). Deliberately creating a slight hook on your edge is sort of received wisdom when tuning for plastic, but this was a very clear demonstration of the effect (and one of our coaches had a similar result last year, at a much higher level than mu meagre efforts, when moving from 5th in a Club National to Grand Prix winner the following day)
Sorry for the thread hijack, NomadicBoo, as this absolutely not relevant to your problem.

GrahamN, I regularly get enquiries from dryslope racers for tools to create a hanging burr.

GrahamN,
Is that not if you have more angle on your guide? or am I thinking of edge angles in 0, 1, 2, 3 degrees and you in 90, 89, 88, 87??

OK, that's one source of the confusion. I would also differ from you in the use of the word "blunt". To me "blunt" means having a rounded edge, so it's perfectly possible to have a) a blunt 87 degree edge or b) a sharp 90 degree edge (rather poor attempt to illustrate follows):
| Code: |
a) / b) |

\___ |____________
|
On hard snow/ice/dry you'll get much better grip from b) than a).

GrahamN, Thought that might be it . I loosely used the tem blunt but that makes sense.
